Exposes the type named `type`, which is the common type of two std::chrono::time_points.

### Member types

`type` | std::chrono::time_point<Clock, typename std::common_type<Duration1, Duration2>::type>

### Notes

The common type of two std::chrono::time_point types is a std::chrono::time_point with the same clock as the two types and the std::common_type of their durations.
